Evolved Gas Analysis and Kinetics of Catalytic and Non-Catalytic Pyrolysis of Microalgae Chlorella sp. Biomass With Ni/θ-Al2O3 Catalyst via Thermogravimetric Analysis

This study investigates the efficacy of a prepared Ni/θ-Al 2 O 3 catalyst during pyrolytic conversion Parachlorella kessleri HY-6 and compares results with non-catalytic conversion. The was characterized by techniques such as Brunauer–Emmett–Teller (BET) for surface area, acidity, X-ray powder diffraction (XRD). Isoconversional combined kinetic methods were used to kinetics process. at 10, 20, 30% algal biomass. addition facilitated lowering mean activation energy pyrolysis. catalytic effect more pronounced lower higher conversions. presence pyrolysis indicated value ∆H, ∆G.
